使用自定义异步中间件进行调度 - Redux Thunk - 响应路由器

我'm trying to dispacth an async action with redux thunk. but my code isn'工作，控制台只是把我的错误 Error: Actions must be plain objects. Use custom middleware for async actions.

好吧，这是我的代码：

import React from 'react';
import ReactDOM from 'react-dom';
import 'babel-polyfill';
import ReduxThunk from 'redux-thunk';
import { createStore, combineReducers,applyMiddleware } from 'redux';
import { Provider } from 'react-redux';
import { Router, Route, IndexRoute, browserHistory } from 'react-router';
import { syncHistoryWithStore, routerReducer } from 'react-router-redux';
import App, { reducer } from './AppContainer';
import {launchReducer} from './modules/Financeiro/Lancamentos/reducer/launchReducer';
import {Rotas} from './routes';

// Add the reducer to your store on the `routing` key
const store = createStore(
    combineReducers({
        app: reducer,
        routing: routerReducer,
        launch: launchReducer
    }),
    applyMiddleware(ReduxThunk),
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__(),
);

// Create an enhanced history that syncs navigation events with the store
const history = syncHistoryWithStore(browserHistory, store);

document.getElementById('app').style['min-height'] = '100vh';

ReactDOM.render(
    <Provider store={store}>
        <Router history={history}>
            {Rotas.map(rota => (
                <Route path={rota.path} component={App}>
                    <IndexRoute component={rota.component} />
                </Route>)
            )}
        </Router>
    </Provider>,
    document.getElementById('app') // eslint-disable-line comma-dangle
);

我的动作代码是这样的：

export const newLaunch = (obj) => async (dispatch) => {
    delete obj.idLaunch_headerOrigin
    let resp = await APIService('http://localhost:3000/launch/newLaunch', obj, 'POST')
    dispatch({type: SET_LAUNCH_HEADER_ORIGIN, payload: resp.response})
  }

在组件中我只是导入动作并从react-redux输入连接，我用“this.props.newLaunch（obj）”调用它

编辑：我的错误是在createStore，创建商店收到3个参数，我有一个错误的顺序将prelaoders放在enchances地方，我只是交换第二个到第三个参数的roder并且它完成了，我的最终代码是： const store = createStore( combineReducers({ app: reducer, routing: routerReducer, launch: launchReducer }), window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__(), applyMiddleware(ReduxThunk), );

谢谢你的帮助，为坏英语而烦恼！
